XK0-005 · Question #1877
A user reports performance degradation on a server that is running their web application. Given the following information about the system: Which of the following describes the ongoing behavior?
The correct answer is C. The web application process is consuming all system memory, causing the system to use swap. The two webapp processes are using nearly all of the 23 GiB of RAM (each ~11.7 GiB), leaving almost no free memory and forcing the system to swap (~1.2 GiB), which degrades performance.
